Cyclization of carbonyl substituted enyne-allenes: C2-C6-cyclization induced by heat or by addition of samarium(II) iodide, samarium(III) chloride, or boron trifluoride

Under a variety of conditions the reaction of enyne-allenes with carbonyl substituents at the allene and phenyl or t-butyl groups at the alkyne terminus afforded products via the new C2-C6-cyclization. Products of the Myers-Saito-cyc
